A total of 37 entries are due to take part in next weekend’s IMSA Michelin Pilot Challenge pre-season test at the Roar Before the Rolex 24.
The entry list includes 24 GS class cars and 13 TCR entries for the test, which unlike the IMSA WeatherTech SportsCar Championship, is not mandatory for competitors.
It means the entry list is expected to grow ahead of the four-hour BMW Endurance Challenge on Jan. 29.
As is the case with the Roar list for Rolex 24 at Daytona competitors, driver lineups have not yet been disclosed although a number of teams have already announced its driving squads.
Among entries of note include a single-car effort from Riley Motorsports, which will give the Toyota GR Supra GT4 its North American debut, while reigning GS class champions KohR Motorsports has only a single Ford Mustang GT4 entered for the test, instead of its Aston Martin Vantage GT4.
Eight of the 13 entries in TCR, meanwhile, are Hyundais, with only a single Audi RS 3 LMS TCR currently due to take part by Roadshagger Racing.
The three day test runs from Jan 22-24.
